  • Why does DEHP form more octanol in water?
  • The probable explanation is that DEHP readily forms more or less colloidal dispersions in water. Natural constituents in water may influence the solubility. A non-colloidal solubility of 0.003 mg/L is chosen for the Risk assessment. The Henry´s law constant for DEHP is 4.43 Pa m 3 /mol. The octanol-water partition coefficient, log Kow, is 7.5.
  • What is DEHP used for?
  • Industrial and commercial uses of DEHP include resilient flooring, wall covering, roofing, aluminium foil coating/laminating, paper coating, extrudable moulds and profiles, electronic component parts, and wire and cable coating and jacketing. Medical devices comprise approximately 25% of total manufacturing use of DEHP in the USA.
  • How much DEHP is consumed in the world?
  • The estimated total consumption of DEHP by geographical region was (thousand tonnes): western Europe, 465; North America, 155; eastern Asia, 490; Japan, 245; and others, 765 ( Towae et al., 1992 ). The global production of DEHP in 1994 was estimated to be between 1 and 4 million tonnes.
  • What is the solubility of DEHP in water?
  • 1.3 PHYSICO-CHEMICAL PROPERTIES DEHP is a colorless liquid at room temperature. The vapour pressure is estimated to 3.4 . 10-5Pa at 20°C. A wide range of values on the water solubility (0.0006 – 1.3 mg/L at 20-25°C) is available in the literature. The probable explanation is that DEHP readily forms more or less colloidal dispersions in water.
  • What happens if a product containing DEHP is used industrially?
  • For the scenario industrial end-use of products containing DEHP, it is assumed that relatively high work temperatures, aerosol generation and considerable skin contact occur.
  • Does glucuronidation increase urinary clearance of DEHP metabolites?
  • Glucuronidation increases urinary clearance of DEHP metabolites, but Koch et al. (2004b, 2005b) noted the absence of glucuronidated MEHP in the blood of the volunteer (results in urine were not reported).
